Good job, Sheldor! You could be right about the IC, but we really don't know...

There are a few more observations:

First, regarding this picture and the challenge course:

See end of the slide table from the previous photo in this photo
After slide table navigate across Teeter Totter (Tai)
Then across the balance beam (Cydney)

There is also a structure that they have to scale over or under after the slide table, then onto the Teeter Totter, then to the balance beam before arriving at the table to find the right numbers. Aubry is well ahead as you can see she has all of her tiles played out on the table already...

What is interesting is there are a pile of tiles on Cydney's table, and there are no tiles on Tai's or Michele's table? Did she have to go back for something? She's been to the table once and dropped off the tiles and missed something?

Then, in the next challenge where they have to complete a tiered tower of blocks, we see that Michele and Tai are at a very similar point in the challenge, while Cydney is behind them. We see Michele and Tai's structures, but we do not see Cydney's structure at all, and she is between Michele and Tai, if she were at the same point as them, we should see her tower in this picture...

Clearly, Michele and Tai are very close, while Cydney is behind, we do not see her blue blocks, but we do see the top of her head, she must be leaning over the table. It appears that the blocks used are different sizes, so they have to use them to create a tower with tiers that is level at all levels. If you are behind this would be an easy challenge to cheat off of someone else structure...(just saying
We do not see Aubry beyond Tai or her structure at all.

On first review it appears that Aubry will win the tiles and number combination challenge, while Michele or Tai looks like they could win the build the tower challenge? But, we don't see Aubry at all...I do think that Aubry has a leg up in the water if there is swimming and/or diving involved....thinking back to her stellar performance in the first IC! So, she could win them both? One thing is clear....it doesn't look like Cydney will win either.
